' ,In GreatBritain April"2 7, 1933 '7 claims. ,(01. 118-47) The invention relates to that type oi yarn-- spinning knownas the ringfiyer system, wherein the spindle is rotated solely" by the {thread" being spun ortwi'sted, an example of which will be {found in the British Patent Specification No.

In this systernfit is usual-to 26,228 of "1904. use a revolving ring or bush Whichhereinafter will be termed a ring flyer driven from-the usual tin rollers or otherwise, and ot-suiii'cient-inter 10 nal diameter, to accommo-date the package of yarn to be built on the spindle in-the form of a cop or bobbins It is also known that to revolve "a ring iiyer lon -the necessary largiebarf i'ng -required for the above mer'itioned condi- 1 183 tionsthe amount of power required isa serious handicap and a drawback due mainly to the viscosity of the lubricating oil, and forthe purpose of mitigating this object ball bearings have also been tried. a -In previous practice, it is customary fjor' the said ring flyerand its bearing.

- 'e object of the-present invention-is an -'im-' proved system of driving said ring fiyers whereby the conditions aforesaid' are obviated, the ten si'on of" the driving bands exert no pull on the flyer' bearings, no lubrication of said bearings is. necessary consequently no soiling or contami- 3 nationof the yarn by lubricant can occur;

frictionjin'the bearings is reduced orleliminater'i;

considerable economies in power are effected,-

and the flyers may berun at a-greatly-increased v I i alternative means tothatshownin Fig. 9], of

rotary speed. v V I I :1 According to 'thepresent invention, the ring flyersiare rotated by' a'balanced'drive. By this is meant. that the frictional contact of the driv ing bands or tapes and 'the motiv'epower there ofpis applied at two diametrically opposite segmental :parts only of the wharve or" the ring' flyers, whereby the'pres'sure andforce applied to one side of the flyer is balanced by equal conditions on the opposite side. Also by means of sl'i'ghtly increasing-"the relative height of the tension pulley 'wharves the band's" or tapes can be made to c'a'rry the weight of the ring flyers,

50. wherebyzthe lattermay be said to be me. floating condition. I V '1 Alternatively, a' balanced drive maybe provided forthe ring flyersby mounting them with out anysupport bearingsthe fiyers being held in their operativepositicns against antiiriction pulleysby the tension of the driving bands and two segmental portions of the flanges of said pulleys. r

Means are alsoprovided on the 'fixed or bolster rail, whereby the whole of the tension pulleys can be moved laterally into therclative different position necessitated by" changing the bandsor tapes when altering the direction of r0- tation of the ring-fiyers, and for holding a part of said means in'the operative position by the tension of the driving band. r

Iattain these objects by the means illustrated in the accompanyin drawings, in which:--

Eig.-1 1 is a 'front elevation of a fragment of' mammary rail associated'with a normal bolst'er rail, showing means whereby the auxiliary rail may be adjusted relative'jto the bolster m1 andlo'cked thereto. 1 1 1 f- ;Similar letters refer tcsimilarpartsthroughout the several views. v v With reference to the drawings, see-Figs. 1, 2, 3,4,7, 8, 9, 10 vand'lll. A is the machine frame. B,"",C, are the customary tin rollers,- D the driving bands or tapes passing over said rollers 'forrotatin'g the ringflyers E mounted on the usual bearings F fitting apertures G in the bolster .rail J isa' lifterrail onwhich are mounted the spindles K on which are wound the cops or bobbins of yarn. In-order to obtain the aforesaid balanced drive means the weight of said pulley and its hous-' for the ring fiyers E with particular reference to Figs. 1, 2, 3 of the drawings, an antifriction or tension pulley L is employed, the wharve of which is less in diameter than the wharves of the flyers. The said tension pulleys correspond in number with the number of ring flyers and each pulley is supported on a footstep M housed in an oil reservoir N for lubricating said pulley bearing, carried by a spring bracket P secured to the front of the rail H, or, to an adjustable auxiliary rail or bar l-I bolted thereto. This spring P is for the purpose of taking up any stretch of the spindle band. Interposed between the outward and the inward portions of each band D at a point intermediate of the roller C and pulley L is situated the flyer E and its bearing F in the rail H. The upper surface of the rollers B, C, the wharves of the flyers E and the wharves of the tension pulleys L are approximately in the same horizontal plane with the bands D returning from the flyer to the roller B at right angles to the latter, and by a different angle on returning from roller C to said fiyer.-

By bisecting the angle formed by the outward and inward portions of said band D as shown by the broken line in Fig. 2 of the drawings, the correct positionis given to the pulleys L relative to the opposing flyers to ensure to the bands an uniform amount of segmental contact with the wharves thereof by the driving band, for giving the desired balanced drive. 7

Alternatively (see Fig. 10 of the drawings),

in place of the housing of the .pulley L being supported by a spring bracket as shown in Fig. 9, it may be carried by a flap R hinging at S on the rail H stop T to prevent the tension on the driving band from raising the wharve of the tension pulley above the plane of the wharve of the fiyer. Should the band become slack by any the pulleys L, the tension of the driving bands is adapted to raise said rings until their castellated bases are clear of their bearings, when said rings .may be said to revolve in a floating condition, as clearly shown in Fig. 10 of the drawings. I

Where it is desired to dispense with bearings for the fiyers (see Figs. 5 and 6 of the draw:- ings) the flyers E are held in position against the antifriction or like pulleys L solely by the pull of the driving bands D, each ring flyer being in frictional contact with two of the said pulleys L, a flange U on the flyer overlapping the top of the pulley; the latter lends support to said flyer and is maintained in its operative position by the pull of the band as before described. s s V v I When the twist given to the yarn is required to be reversed, the bands D between the roller 0 and the flyers are turned, causing the direc-' tion ofdrive of the flyers E to be reversed (as clearly shown by arrows in Fig. 4 of the drawings); this gives an opposite twist'to the yarn being spun.

In order to preserve the angle of engagement by the bands D with the wharves of the ilyers according to whether a right or a left hand twist is to be given to the yarn, the rail H is pro- The flap is providedwith a vided near each end with a slot V within which functions an eccentric W provided with a handle X for rotating same, the axle of eccentric W being housed in the bolster rail. The turning of one of these handles rotates the eccentric in its housing in rail H causing said rail to be moved to the right or left, as shown in broken lines in Fig. 11 of the drawings, for the purposes aforesaid. Bolts Y operating in slots Z in the rail H are adapted to lock said rail in position after adjustment.

The ring flyer is preferably composed of vulcanite, ebonite or other suitable light material, but it may be made of metal, or a combination of metal and other material such as an aluminium fiyer with a vulcam'te inner bush, or a vulcanite flyer with a metal wharve, and castellations E may be formed on the underside of said flyer for reducing the friction thereof when in contact with its bearing. E are thread guides fixed on opposite sides in the ring flyer.
